Ning Zhang commented on HIVE-1359:
----------------------------------
Discussed offline with Namit, John, and Paul. We need to generalize the unit
test framework to improve code coverage. Uploading a design doc unit_test.txt
for review.
> Unit test should be shim-aware

> Some features in Hive only works for certain Hadoop versions through shim.
> However the unit test structure is not shim-aware in that there is only one
> set of queries and expected outputs for all Hadoop versions. This may not be
> sufficient when we will have different output for different Hadoop versions.
> One example is CombineHiveInputFormat wich is only available from Hadoop
> 0.20. The plan using CombineHiveInputFormat and HiveInputFormat may be
> different. Another example is archival partitions (HAR) which is also only
> available from 0.20.
